5. Many sciences rely on observation instead of (or in addition to) designed experiments. Compare the data quality issues involv

ed in observational science with those of experimental science and data mining
Biology

Answer and Explanation:

The quality of the data can be higher in observational or experimental studies depending on the subject being researched.

In a way, we can think that experimental studies have better data quality, due to the design of the experiment and the control of the study groups and the variables that are not possible to be established in the obsevational experiments.

However, in the case of studies of abstract subjects, the experimental study ceases to provide high quality activities, and it is necessary to establish an observational study so that efficient data can be promoted.

Significant amounts of phosphorus are found in all locations on Earth except the..
Eduardwww [97]

Answer:

Atmosphere

Explanation:

Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.

What factors that influence mass movement of particles
natka813 [3]

Mass movement, which is sometimes called <em>waste movement</em> or <em>slope movement, </em>is defined as the large movement of rock, soil and debris downward due to the force of gravity.

<h3>Factors affecting mass movement </h3>

1.  Slope  

    - Gravity provides the energy to move the materials.  

    - Rapid movements (e.g. landslide, slumping) etc.

2.  Water

     - Rainwater acts as a lubricant to weathered materials.  

     - Rainwater adds weight to weathered materials.  

3.   Rock structure  

     - Joints dipping downslope usually assists landslides, rockfalls, rockslide etc

4.  Vegetation  

     - Lack of vegetation cover to hold the loose particles.  

5.  Vibrations  

     - Earthquakes.  

     - Construction processes and mining operations.

Question 1
MArishka [77]

Physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.

<h3>What do you mean by Physical changes?</h3>

Physical changes may be defined as those changes which appeared physically like color, odor, texture, mass, and density.

Chemical changes may lead to the formation of new chemicals with definite properties. It involves when the chemical identity of any substance may alter.

Therefore, physical and chemical changes may be similar because neither can change the number of atoms of each element that are present.
